A. HOUGHTON, OF PUTNAM, CONNECTICUT, ASSIGNOR TO HIMSELF, AND EBENEZERD. DRAPER AND GEORGE DRAPER, OF MILFORD, MASSACHUSETTS.

SPINNING-FRAME.

Specification of Letters Patent No. 20,920, dated July 13, 1858.

T0 all whom t may concern:

Be it known that I, AMASA HOUGHTON, of Putnam, in the county of vWindhamand State of Connecticut, have invented an Improved Bolster for Spindlesof Spinning- Frames; and I do hereby declare that the same is fullydescribed and represented in the following specification and theaccompanying drawings, of which- Figure l, denotes a front elevation,and Fig. 2, a vertical section of a spindle and a bolster rail having myimprovement applied to them.

The ordinary bolster of the upright spindle is nothing more than eithera narrow hole through the bolster rail or a tube projecting through andfrom the said rail, the spindle passing through the bolster andrevolving therein when in use. In lubricating such a bolster, much wasteof oil is experienced, as the oil on being poured into the bolster canflow freely downward between the same and the spindle, and run down onvthat part of the spindle which is below the bolster.y The result is,that with a spindle having a revolution of six thousand times in aminute, it will be necessary to apply oil to the bolster about threetimes in each twelve hours, or once every four hours while 'it may be inoperation.

My invention not only effects a great saving of oil, but experience hasdemonstrated that when it is applied to a spindle, the latter may be runabout four weeks with butI once oiling.

The nature of my invention consists in combining' and arranging with theupright spindle and bolster a cup or oil receptacle vsuch being made toextend below and concentrically around the bolster and to project fromthe spindle.

In the drawings, A denotes the spindle; B, the bolster rail; C, thebolster extending through and below the bolster' rail and formed tubularand with the lower portion of its outer surface taperingas shown at a,a, in Fig. 2. The spindle works in the bolster in the usual way, and hasa cup D, extending from it and around it and the bolster, thearrangement of such cup being as shown in Figs. l, and 2, a shoulder b,Z), of the bolster serving as a cap or cover to the cup while thespindle is in use. rIhe upper part of the bolster is grooved around thespindle or formed in the ordinary way with a channel c, for reception ofoil.

In the operation of my invention, the lubricating Huid when lpoured intothe channel c, will flow down between the bolster and the spindle andinto the cup D. When the spindle is putin rapid revolution the oilwithin the cup by reason of the action of centrifugal force will be madeto rise up, more or less between the spindle and the bolster, and so asto keep th-e rubbing surfaces continually lubricated.

That I claim as my invention is- The application of t-he cup to theupright, spindle and the bolster so as to operate lherewithsubstantially in manner as speci- In testimony whereof, I have hereuntoset my signature.

AMASA HOUGH'ION.
